Design And Implementation Of Platform For Academic Exchanges Based On The Three-tier Architecture

With the continuous development of network technology and information technology, information industry is accelerating the pace of building more and more rely on the daily work required to complete Web application, academic exchange unit is no exception. I units and subordinate units distributed in 10 provinces and cities, in addition to the work of professional and strong, the ability to research technical staff is also high, to enhance the technical level of the Department of scientific research personnel, break time and space constraints, to create a good academic atmosphere,so as to better serve their own work, the unit intends to build a LAN-based development platform for academic exchanges, academic exchanges work to achieve industry expert lectures live, on demand as well as other academic information query download function, help me work in modern research unit construction.In academic communication work to the unit, this paper has a detailed research on the basis of comprehensive units relevant opinions, according to the project development process, completed the demand analysis of the platform. On the basis of the needs analysis focuses on the key technology and development platforms to achieve. Platform in the development of the use of PHP technology, combined with MySQL database technology, using Apache as the Web server, designed and implemented a three-layer structure having a pattern of live video capabilities and scientific and technical information query download academic exchange website.Paper demand platform analysis, design, implementation, testing each step is described in detail, and ultimately develop academic exchange platform of academic exchange dynamic publishing capabilities, query Lectures live video function,academic exchange data download function, research Exhibiting function, rendering style gold scientific research, academic exchanges garden feature. Wherein Lectures video live and on-demand using Windows MediaEncoder academic exchange live audio and video collection, with Windows MediaServer video release, then live and on-demand streaming media content embedded into HTML web pages, users can use IE, FireFox and other browsers login watch.This article is designed to develop academic exchange platform to enable all LAN users can watch live query expert lectures and related academic information through the browser visit the website, compared with the traditional academic model to improve the academic performance. In addition, in view of the platform in the form of functional modules to develop, load, it enhances its maintainability and scalability,maintenance and upgrading work of academic exchange platform to provide favorable conditions.
